Telescoping shipping boxes are made as two pieces an inner box which is the bottom piece and the outer box which is the topper or lid. Telescoping boxes are great for packing large panels and other low profile bulky products that are challenging to package.
Telescopic boxes offer convenient flexibility to any packing department, because the way the separate lid slides over the base allows you to vary the height of the final carton depending on the contents. Of course, where the lid does go over the base, you’re also getting double the amount of rigidity on the sides that would get with a normal carton, offering even greater protection to your product.
